Piece of garlic (5)
I believe the answer is:
'piece of garlic' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for clove that I've seen before include "Aromatic bud" , "Split; spice" , "A spice; a garlic bulb" , "Spicy bud - section of garlic" , "Garlic segment" .)
